Have you ever wondered how inkjet printers work? Are you amazed each time there is a copy of your document emerging from a printer? Inkjet printers are the most commonly used printers in the world. The way they work is that the printer sprays drops of ink on the paper through tiny holes on the print head. Inkjet printers are not that complicated and are fairly cheap. They find their use among those who do not require a high quality of printing like students, office workers, and those who use them at home. One of the downside of this type of printer is that it uses cartridges, and thus you will have to be constantly refilling them. Before you buy such printer make sure to find a place where you can buy cartridges at a low price, or choose a printer that uses ink more efficiently.
